The Snapdragon 875G is reportedly confirmed to be made by Samsung
The Snapdragon 8xx series of premium mobile-device processors has sprouted Plus variants over the last few years. Now, it seems that it will also gain 8xxG spin-offs as well. Their reported first generation may, as with the 765G and 720G, be touted as better optimized for intensive smartphone tasks (read: gaming, as suggested by their new suffix).
Their new highest-end counterpart is currently thought to launch in late 2020 so as to be ready for the ultra-premium and (possibly) Android gaming flagships of the following year. Accordingly, it is to be called the 875G, and is likely to be built on a 5 nanometer (nm) process. A Chinese media outlet claims to have broken news that confirms rumors of Samsung being the foundry that will put it into mass production.
An earlier report also indicated the same; however, the South Korean giant was also apparently still in contention with TSMC for this major Qualcomm order at the time. However, the Taiwanese foundry has reportedly been beaten out for the deal, netting Samsung no less than 1 trillion won (US$846 million) in the process.
